Abstract : Replacement windows with structural elements composed of polyvinyl chloride compound have been examined to determine their performance and energy conserving potential. Life cycle costing procedures and a mathematical model have been presented for use in comparing different windows. These methods should be carefully followed as it was not possible to generalize on the suitability of any specific type of window. The major factors which influence window selection include installed cost, air infiltration and maintenance. It was surprising to find that a window's thermal transmittance coefficient, 'U' value, had only a small impact on the economic evaluation. (Author)
